TECHNICAL NOTICE:
5P2R series pumps are centrifugal
pumps which are in most applica-
tion's being combined with swim-
ming pool filters on swimming pool's.
In some cases are the pumps instal-
led without filter.
This installation instruction is being
made up for the later application.
Only qualified, licensedpersonnel should installpump and wiring.
PUMP MOUNT MUST:
E Be solid - Level - Rigid - Vibration
free. (To reduce vibration and pipe
stress, bolt pump to mount.)
E Allow pump suction inlet height to
be as close to water level as possible.
E Allow use of short, direct suction
pipe (To reduce friction losses).
E Allow for gate valves in suction
and discharge piping.
E Have adequate floor drainage to
prevent flooding.
E Be protected from excess
moisture.
E Allow adequate access for servi-
cing pump and piping.
NOTICEUse Teflon tape for making all threa-
ded connections to the pump. Do not
use pipe dope; pipe dope will cause
stress cracking in the pump.
NOTICEPump suction and discharge connec-
tions have molded in thread stops. Do
not try to screw pipe in beyond these
stops.
TEFLON TAPING INSTRUCTIONS:
E Use only new or clean PVC pipe
fittings.
E Wrap male pipe threads with one
to two layers of Teflon tape. Cover
entire threaded portion of pipe.
E Do not overtighten or tighten past
thread stop in pump port!
E If leaks occur, remove pipe, clean
off old tape, rewrap with one to two
additional layers of tape and remake
the connection.
NOTICE
Support all piping connected with
pump!
PIPING
E Use at least 1 1/2" PVC pipe with 5"
trap. Increase size if a long run is nee-
ded.
E To avoid strains on the pump, sup-
port both suction and discharge pipes
independently. Place these supports
near the pump.
E To avoid a strain left by a gap at
the last connection, start all piping at
the pump and run pipe away from the
pump.
E Never use a suction pipe smaller
than pump suction connection.
E To avoid airlocking, slope suction
pipe slightly upward toward the pump.
NOTICE
To prevent flooding when removing
pump for service, all flooded suction
systems must have gate valves in suc-
tion and discharge pipes.
ELECTRICALHave the pump connected by a
licensed electrican according
to the national standards.
Three phase models must be
protected by a control box.
Ground motor before connec-
ting to electrical power sup-
ply! Failure to ground motor can
cause severe or fatal electrical
shock hazard!
Do not ground to a gas supply
line!
To avoid dangerous or fatal
electrical shock, turn OFF
power to motor before working on
electrical connections.
Ground Fault Circuit Interrup-
ter (GFCI) tripping indicates an
electrical problem. GFCI trips and will
not reset, have a qualified electrician
inspect and repair electrical
system.
Exactly match supply voltage
to nameplate voltage! Incor-
rect voltage can cause fire or serious-
ly damage motor and voids warranty!
If in doubt consult a licensed
electrician.
- 5P2R - Page 5
Installation
VOLTAGE
E Voltage at motor must be not more
than 5% above or below motor name-
plate rated voltage or motor may
overheat, causing overload tripping
and reduced component life. If volta-
ge is less than 90% or more than 110%
of rated voltage when motor is run-
ning at full load, consult power com-
pany.
GROUNDING/BONDING
E Install, ground, bond and wire mo-
tor according to local or National El-
ectrical Code requirements.
E Permanently ground motor. Use
ground terminal, use size and type
wire required by code. Connect motor
ground terminal to electrical service
ground.
WIRING
E Pump must be permanently
connected to circuit; be sure no other
lights or appliances are on the same
circuit.
NOTICETo prevent dirt, rain, bugs, etc., from
entering motor when not wiring with
conduit, he sure to seal wire opening
on end of motor.
E Use Ground Fault Circuit Interrup-
ter (GFCI) as master on-off switch; it
will sense a short circuit to ground
and disconnect power before it beco-
mes dangerous to pool users. Test ac-
cording to maker's instructions.
E In case of powar outage, check
GVDCI for tripping (which will prevent
normal water circulation). Reset if ne-
cessary.
FITTINGS
E Fittings restrict flow; for best effi-
ciency use fewest possible fittings.
E Avoid fittings which could cause
an air trap.
E Pool fittings must conform to Inter-
national Association of Plumbing and
Mechanical Officials standards.
E Use only non-entrapping suction
fitting or double suction.
CAUTIONNEVER run pump dry! Running
pump dry may damage seals,
causing leakage and flooding! Fill
pump with water before starting mo-
tor.
Before removing trap cover:
1. STOP PUMPbefore proceeding.
2. CLOSE GATE VALVESin suction and discharge
pipes.
3. RELEASE ALL PRESSUREfrom pump and piping
system.
4. NEVER tighten or loosenclamp while pump is
operating!
If pump is being pressure tes-
ted, be sure pressure has been
releases before removing trap cover!
Do not block pump suction!
To do so with body may cause
severe or fatal injury. Small children
using pool must always have close
adult supervision!

Installation Operation
PRIMING PUMP
E Release all air from filter and
piping system: see filter owner's
manual.
E In a flooded suction system (water
source higher than pump), pump
will prime itself when suction and
discharge valves are opened.
E If pump is not in a flooded suction
system, unscrew and remove trap
cover; fill trap and pump with water.
E Lubricate trap cover "0" Ring with
petroleum jelly each time it is
removed.
E Clean and inspect "0" Ring;
reinstall on trap cover.
E Replace trap cover on trap; turn
clockwise to tighten cover.
NOTICETighten trap cover by hand only (no
wrenches)! Use a wrench only if ne-
cessary to remove lid!
Pump should prime now. Priming
time will depend on vertical length
of suction lift and horizontal length
of suction piping.
E If pump does not prime, make
sure that all valves are open,
suction pipe end is under water
and that there are no leaks in
suction pipe. See Troubleshooting
Guide, Page 10.
STORAGE/WINTERIZING
NOTICEAllowing pump to freeze will damage
pump and void warranty! NOTICE: Do
not use anti-freeze solutions (except
propylene glycol) in your pool/spa
system. Propylene glycol is non-toxic
and will not damage plastic system
components; other anti-freezes are
highly toxic and may damage plastic
components in the system.
E Drain all water from pump and pi-
ping when expecting freezing tempe-
ratures or when storing pump for a
long time (see instructions below).
E Keep motor dry and covered
during storage.
E To avoid condensation/corrosion
problems, do not cover pump with
plastic.
E For outdoor/unprotected installations:
1 . Enclose entire system in a
weatherproof enclosure.
2. To avoid condensation/corrosion
damage, allow ventilation; do not
wrap system in plastic.
DRAINING PUMP
1. Pump down water level below all
inlets to the pool.
To avoid dangerous or fatal
electrical shock hazard, turn
OFF power to motor before draining
pump.
2. Remove trap cover and use low
pressure air to blow accumulated wa-
ter from the piping system. Use a STA-
RITE U79-11 Lid Wrench to remove
trap covers that have been over-
tightened or have taken a set and
cannot be removed by hand.
3. Cap inlet piping after draining to
keep water out of the pipes.
4. To prevent pump from freezing, re-
move trap cover and drain the tank
body through the drain plug (Key No.
18, Page 11). Clean pump thoroughly;
replace trap cover.
NOTICETighten trap cover by hand only (no
wrenches)! Use a wrench only if ne-
cessary to remove cover!
5. Be sure motor is kept dry and
covered.
STARTUP FORWINTERIZED EQUIPMENT
1. Remove any temporary weather
protection placed around system for
shutdown.
2. Follow filter manufacturer's in-
structions for reactivation of the filter.
3. Inspect all electrical wiring for da-
mage or deterioration over the shut-
down period. Have a qualified servi-
ceman repair wiring as needed.
4. Inspect and tighten all watertight
connections.
5. Open all valves in suction and
return piping.
6. Remove any winterizing plugs in
piping system.
7. Drain all antifreeze from system.
8. Close all drain valves and replace
all drain plugs in piping system.
9. Prime pump according to
instructions on Page 7.

Operation
CAUTIONPump should only be servi-ced by qualified personnel.
Be sure to prime pump (Page 7)before starting.
Before removing clamp or
trap cover:
1. STOP PUMP before pro-
ceeding.
2. CLOSE GATE VALVES in
suction and discharge pipes.
3. RELEASE ALL PRESSUREfrom pump and piping system.
4. NEVER tighten or loosen clamp
while pump is operating!
To avoid dangerous or fatalelectrical shock hazard,
turn OFF power to motor beforeworking on pump or motor!
E Aside from lubricating trap cover
0-Ring, no lubrication or regular main-
tenance is needed beyond reasonable
care and periodic cleaning.
E If shaft seal is worn or damaged,
repair as follows:
Pump Disassembly/Removing Old Seal:
Disconnect power to pumpmotor. Release all pressure
by opening all vents before star-ting work. Be sure gate valves on suctionand return piping are closed befo-re starting work.
1. Drain pump by removing drain
plugs on bottom of pump body and
trap body.
2. Be sure there is no pressure in trap
body; remove cover (unscrew by tur-
ning counterclockwise).
3. Remove clamp holding pump
halves together.
4. Remove pump base mounting bolts,
if used. Motor and seal plate assem-
bly can now be pulled away from
pump body.
5. Remove five screws and washers
holding diffuser to seal plate. Remove
diffuser.
6. Remove motor canopy. Being care-
ful not to touch capacitor terminals,
loosen capacitor clamp and move ca-
pacitor to one side.

PUMP REASSEMBLY/INSTALLING NEW SEAL:
1. Ceramic seat must be clean and
free of dirt, grease, dust, etc. Wet ou-
ter edge of "0" Ring with small amount
of liquid detergent; press ceramic
seat into seal plate cavity firmly and
squarely with finger pressure.
2. If ceramic seat will not locate pro-
perly, remove it, place face up on
bench and reclean cavity. Ceramic
seat should now locate.
3. If seat still will not locate properly,
place a cardboard washer over the
polished face and use a piece of
3/4" standard pipe for pressing
purposes (Fig. 3).
NOTICEBe sure not to scratch or mar polished
surface or seal will leak.
4. Remount seal plate on motor. Tigh-
ten bolts to 60-80 inch-Ibs. torque.
5. Apply a small amount of liquid de-
tergent to inside diameter of rotating
half of seal.
6. Slide rotating member, polished
face first, over threaded shaft end and
shaft shoulder until rubber drive ring
hits shaft shoulder (Fig. 4).
NOTICEBe sure not to nick or scratch polis-
hed seal face; seal will leak if face is
damaged.
7. Screw impeller onto shaft (clock-
wise); this will automatically locate
seal in seal plate.
8. Mount diffuser on seal plate; tigh-
ten screws to 10-14 inch-ibs. torque.
9. Assemble motor and seal plate to
volute; be sure clamp is properly
seated.
NOTICEClamp knob can be located in any po-
sition around volute; if it is moved af-
terassembly, tighten knob while
tapping around clamp to assist
sealing. Do not move clamp while
pump is full of water.
10. Reinstall pump base mounting
bolts (if used) and prime pump
according to instructions on Page 7.
INSTALLING HEAT SINK INSERT:
If the heat sink insert moves or shifts
during seal removal, remove and rein-
stall it to prevent leakage.
1.To remove heat sink insert, grasp
with fingers at the large end and move
back and forth. Do not deform.
2. Replace heat sink insert as follows:
A. Clean off old sealant and foreign
material; clean out insert cavity.
B. Apply a small amount of nonharde-
ning silicone FITV on surface of insert

Failure To Pump;Reduced Capacity Or Discharge Pressure
Suction leakks/lost prime
1. Pump must be primed; make sure
that pump volute and trap are full of
water. See priming instructions,
Page 7.
2. Make sure there are no leaks in
suction piping.
3. Make sure suction pipe inlet is well
below the water level to prevent pump
from sucking air.
4. If suction trap gasket is defective,
replace it.
5. Suction lift of 15 to 25 feet will re-
duce performance. Suction lift of
more than 25 feet will prevent pum-
ping and cause pump to lose prime. In
either case, move pump closer (verti-
cally) to water source. Make sure
suction pipe is large enough.
Clogged pipe/traplimpeller,worn impeller
6. Make sure suction trap is not clog-
ged; if it is, clean trap and strainer.
7. Make sure impeller is not clogged
(follow steps 1 through 7 under "Re-
moving Old Seal", Page 8; check im-
peller for clogging; follow steps 7
through 11 under Installing New Seal",
Page 9, for reassembly).
8. Impeller and diffuser may be worn.
If so, order replacement parts from
Repair Parts List, Pages 11-12.
9. Pump may be trying to push too
high a column of water If so, a "higher
head" pump is needed.
Electrical
10. Pump may be running too slowly;
check voltage at motor terminals and
at meter while pump is running. If low,
see wiring instructions or consult po-
wer company. Cheek for loose con-
nections.
11. Pump may be too hot.
A. Check line voltage; if less than 90%
or more than 110% of rated voltage
consult a licensed electrician.
B. Increase ventilation.
C. Reduce ambient temperature.
D. Tighten any loose connections.
Mechanical TroublesAnd Noise
1. If suction and discharge piping are
not adequately supported, pump as-
sembly will be strained. See Installa-
tion", Page 5.
2. Do not mount pump on a wooden
platform! Securely mount on concrete
platform for quietest performance.
